Best Shopify Email Marketing Apps for Customer Retention in 2026
Retention is the result of a good customer experience, not a sequence alone. Email can help by making product use easier, surfacing relevant next purchases, and returning at a helpful moment.
Measure repeat purchase by cohort, time to second order, contribution margin, refunds, and customer support contacts. Use a holdout when possible and separate natural repeat buyers from customers whose behavior changed after the campaign.
